Show HN: Libmui is a macOS Classic widget lib for Linux Not sure if I would post this for the last day of #marchintosh OR wait for tomorrow the 1st of April. Both apply equally. Anyway, here's a pet project of mine, I made it as a glued on for another pet project of mine, but it developed a life of it's own now and can soar skyward toward success, fame, and glory. https://ift.tt/sxp9tfR April 1, 2024 at 01:03AM

Show HN: FaceLandmarks – ARKit Face Mesh Vertex Tool https://ift.tt/EI238gw

Show HN: FaceLandmarks – ARKit Face Mesh Vertex Tool Hey everyone. FaceLandmarks.com is a little project I put together last weekend, while working with Apple's ARKit for iOS face tracking. For those not familiar, since iOS 11 and A9 processor was released, all iPhones (i.e. iPhone 6s and newer) support augmented reality capabilities. When tracking a face using the front camera and the ARKit framework, a face mesh is generated using exactly 1,220 vertices that are mapped to specific points on the face. These vertices are accessible through ARFaceGeometry, ARFaceAnchor, and ARSCNFaceGeometry within ARKit, and provide a foundation for developers to do facial tracking for common use cases like: social media filters, accessibility, avatars, virtual try on, etc. While the ARKit's tech is impressive and has a smooth DX, the most frustrating part for me was identifying the vertex indexes for specific points on the face mesh model. Apple does not provide a comprehensive mapping of these vertices, besides a handful of major face landmarks. Vertex 0 is on the center upper lip, for example, but there is seemingly little rhyme or reason for the vertex mapping. While devs could download the vertex mapping, open up with a 3d rendering software, and identify vertex indexes (which is what I originally did), I decided to make a simple web app which simplifies this process. FaceLandmarks.com uses Three.js to render a model of the face mesh, with clickable vertices so you can zoom, pan, and easily identify its vertex. In the future, I hope to continue adding semantic labels for each vertex (there are about 2 dozen so far) for searchability. It was a fun afternoon project and hope it may be helpful to others in this niche case. Enjoy! https://ift.tt/YJr2wby March 30, 2024 at 11:18PM

Introducing Applications for Our Scooter Share Program – and Celebrating Wins Shaped by Your Feedback

Introducing Applications for Our Scooter Share Program – and Celebrating Wins Shaped by Your Feedback
By Maddy Ruvolo

Scooters are an important part of San Francisco’s multimodal transportation network.

We’re excited to open applications for the FY2025 – FY2026 Powered Scooter Share Program. This program supports the city’s goal of providing multiple reliable transportation options to get around San Francisco. 

The current permits for scooter share operators expire in June 2024. The next round will go into effect on July 1, 2024.  

For operators who want to apply to the Powered Scooter Share program: 

  • See the FY2025 – FY2026 Powered Scooter Share Program webpage for application materials. 

  • Check out the bottom of this blog for a section with more details about the process. 

Scooter program successes: how your feedback helped 

Over the past several years, we have reached out to stakeholders in a variety of ways to gather feedback on our shared scooter program.  

There have been concerns about sidewalk riding and improper scooter parking. These included cases where scooters block the path of travel for people walking or using mobility devices. We also heard feedback about the need for better adaptive scooter options.  

We considered this community feedback and have revised our application process. We’ve made improvements in the following areas. 

Scooter safety 

We launched campaigns and changed policies to protect people who walk, roll and take transit. 

  • Educational campaign 

Our educational campaign is aimed at people who ride shared scooters and/or privately-owned ones. This campaign includes information about how to ride safely. See our scooter safety campaign blog for details. 

  • Safe parking incentive policy  

We also thought deeply about incentives that might inspire safer behavior. We instituted an incentive program that motivates scooter companies to move improperly parked scooters quickly. If scooter companies respond faster to complaints of improperly parked scooters, the fines they face are reduced. This has resulted in huge wins for safety.  

The average response time to complaints of improperly parked devices dropped from six hours to one hour.  

See the Safe Micromobility Parking Policy webpage for more information. 

  • Sidewalk detection technology 

Our transportation code now requires that all shared scooter devices have sidewalk detection technology. This technology slows down shared scooters if riders use them on the sidewalk. The scooters emit an audible alert, and the scooter share companies are required to send us a monthly report of sidewalk riding.  

This helps us understand where sidewalk riding happens most frequently, so we can send our enforcement team to those hotspots.

Scooter accessibility 

We have received extensive feedback on our adaptive scooter programs. We did this by holding events in partnership with AccessSFUSD and scooter share companies and by soliciting feedback from the Multimodal Accessibility Advisory Committee and the Mayor’s Disability Council. 

For more information, see our blog on partnering with AccessSFUSD. You can also check out our blog highlighting an adaptive scooter event with our current permittees. 

  • Prioritizing adaptive devices 

We’re prioritizing more seated devices and those with greater stability. This can include devices with larger wheels, backrests, floorboards, and other adaptive features. Continuing a requirement from the current permit cycle, all scooter operators in our program will have to offer seated scooters as part of their on-street fleets.  

We are continuing our separate Adaptive Scooter Program, as well. The program includes new requirements based on community feedback to increase usability, such as extending required rental hours so that adaptive scooters can more easily be used for commuting. 

Scooter affordability 

We’re ensuring that people of all income levels can benefit from our shared scooter program.  

For shared scooter riders with incomes at or below 200% of the federal poverty guidelines: 

We require all scooter share permittees to offer low-income plans that waive any applicable scooter deposit. They must also offer a minimum of 50% discount off rental fees or unlimited trips under 30 minutes. Additionally, they must provide a cash payment option. 

Want to provide feedback?

We encourage you to tell us what you think of these improvements and continue giving us feedback. To get in touch about the shared scooter program, you can email ScooterShare@SFMTA.com. 

About the Application 

If you’re interested in applying to become an operator in our shared scooter program: 

The deadline to apply is April 26, 2024.  

We will hold a Question & Answer session on April 5 at 2p.m. Applicants must submit questions in writing to ScooterShare@SFMTA.com by 12p.m. on April 3. 

Applications will be evaluated against a standardized evaluation scorecard to determine the strongest proposals. We expect to issue new scooter permits to applicants that meet San Francisco’s high standards for safety, equity, accessibility and accountability.  

We anticipate announcing successful applicants later this spring, and the new two-year permits will take effect on July 1, 2024.
